Within Firefox, I’m looking for a way to show which HTML elements are used how many times on the current page.
It must display all used HTML elements (even invalid ones) and their count (→ sorted), e.g. like:
16 div
13 span
7 a
5 p
3 h1
2 article
2 h2
1 body
1 head
1 html
1 spoiler
It would be nice if it also takes elements removed/added by JavaScript into account; at best it should simply use the current DOM of when I start the tool.
I’d prefer an extension (displayed in the sidebar), but I’m open for other solutions (bookmarklet?). Displaying the list should not require more than a click or key combo.
A solution must be FLOSS.
